Swaras within a sangathi

 Is there a standard way to represent the notes within a Sangathi like a-A-a-a-A-A?

You should have it in your mind. 
It might seem like a brush off. But then, I visualized a ruled notebook with each line representing a note, 
  and the sequence of the notes placed on the lines.

Now, during singing, I make A-a-A-A-a hit the notes on the lines on the notebook, 
 and there was total clarity in hitting the notes. 

I am sure there are more standard methods than that, but that something new.
